On the energetic origin of self-limiting trenches formed around Ge/Si quantum dots

, 2004
At high growth temperatures, the misfit strain at the boundary of Ge quantum dots on Si(001) is relieved by formation of trenches around the base of the islands.

Grain orientation design via gradient strain path for enhanced strength-ductility synergy in AZ31 Magnesium alloy sheets

Journal of Magnesium and Alloys
The room-temperature ductility of magnesium (Mg) alloys is fundamentally limited by preferential basal slip activation—a challenge directly addressable through strategic grain orientation tailoring.

Coronal Shock Waves, EUV Waves, and Their Relation to CMEs. III. Shock-Associated CME/EUV Wave in an Event with a Two-Component EUV Transient

, 2011
On 17 January 2010, STEREO-B observed in extreme ultraviolet (EUV) and white light a large-scale dome-shaped expanding coronal transient with perfectly connected off-limb and on-disk signatures. Veronig et al. (2010, ApJL 716, 57) concluded that the dome

Spatial and polarization structure in micro-dome resonators: effects of a Bragg mirror

, 2004
Micro-domes based on a combination of metallic and dielectric multilayer mirrors are studied using a fully vectorial numerical basis-expansion method that accurately accounts for the effects of an arbitrary Bragg stack and can efficiently cover a large ...
